12 Great Gifts from Astronomy
This is a season where our thoughts turn to others and many exchange gifts with friends and family. For astronomers, our universe is the gift that keeps on giving. We’ve learned so much about it, but every question we answer leads to new things we want to know. Stars, galaxies, planets, black holes … there are endless wonders to study.
In honor of this time of year, let’s count our way through some of our favorite gifts from astronomy.
Our first astronomical gift is … one planet Earth
So far, there is only one planet that we’ve found that has everything needed to support life as we know it — Earth. Even though we’ve discovered over 5,200 planets outside our solar system, none are quite like home. But the search continues with the help of missions like our Transiting Exoplanet Survey Satellite (TESS). And even you (yes, you!) can help in the search with citizen science programs like Planet Hunters TESS and Backyard Worlds.
Our second astronomical gift is … two giant bubbles
Astronomers found out that our Milky Way galaxy is blowing bubbles — two of them! Each bubble is about 25,000 light-years tall and glows in gamma rays. Scientists using data from our Fermi Gamma-ray Space Telescope discovered these structures in 2010, and we're still learning about them.
Our third astronomical gift is … three types of black holes
Most black holes fit into two size categories: stellar-mass goes up to hundreds of Suns, and supermassive starts at hundreds of thousands of Suns. But what happens between those two? Where are the midsize ones? With the help of NASA’s Hubble Space Telescope, scientists found the best evidence yet for that third, in between type that we call intermediate-mass black holes. The masses of these black holes should range from around a hundred to hundreds of thousands of times the Sun’s mass. The hunt continues for these elusive black holes.
Our fourth and fifth astronomical gifts are … Stephan’s Quintet
When looking at this stunning image of Stephan’s Quintet from our James Webb Space Telescope, it seems like five galaxies are hanging around one another — but did you know that one of the galaxies is much closer than the others? Four of the five galaxies are hanging out together about 290 million light-years away, but the fifth and leftmost galaxy in the image below — called NGC 7320 — is actually closer to Earth at just 40 million light-years away.
Our sixth astronomical gift is … an eclipsing six-star system
Astronomers found a six-star system where all of the stars undergo eclipses, using data from our TESS mission, a supercomputer, and automated eclipse-identifying software. The system, called TYC 7037-89-1, is located 1,900 light-years away in the constellation Eridanus and the first of its kind we’ve found.
Our seventh astronomical gift is … seven Earth-sized planets
In 2017, our now-retired Spitzer Space Telescope helped find seven Earth-size planets around TRAPPIST-1. It remains the largest batch of Earth-size worlds found around a single star and the most rocky planets found in one star’s habitable zone, the range of distances where conditions may be just right to allow the presence of liquid water on a planet’s surface.
Further research has helped us understand the planets’ densities, atmospheres, and more!
Our eighth astronomical gift is … an (almost) eight-foot mirror
The primary mirror on our Nancy Grace Roman Space Telescope is approximately eight feet in diameter, similar to our Hubble Space Telescope. But Roman can survey large regions of the sky over 1,000 times faster, allowing it to hunt for thousands of exoplanets and measure light from a billion galaxies.
Our ninth astronomical gift is … a kilonova nine days later
In 2017, the National Science Foundation (NSF)’s Laser Interferometer Gravitational-Wave Observatory (LIGO) and European Gravitational Observatory’s Virgo detected gravitational waves from a pair of colliding neutron stars. Less than two seconds later, our telescopes detected a burst of gamma rays from the same event. It was the first time light and gravitational waves were seen from the same cosmic source. But then nine days later, astronomers saw X-ray light produced in jets in the collision’s aftermath. This later emission is called a kilonova, and it helped astronomers understand what the slower-moving material is made of.
Our tenth astronomical gift is … NuSTAR’s ten-meter-long mast
Our NuSTAR X-ray observatory is the first space telescope able to focus on high-energy X-rays. Its ten-meter-long (33 foot) mast, which deployed shortly after launch, puts NuSTAR’s detectors at the perfect distance from its reflective optics to focus X-rays. NuSTAR recently celebrated 10 years since its launch in 2012.
Our eleventh astronomical gift is … eleven days of observations
How long did our Hubble Space Telescope stare at a seemingly empty patch of sky to discover it was full of thousands of faint galaxies? More than 11 days of observations came together to capture this amazing image — that’s about 1 million seconds spread over 400 orbits around Earth!
Our twelfth astronomical gift is … a twelve-kilometer radius
Pulsars are collapsed stellar cores that pack the mass of our Sun into a whirling city-sized ball, compressing matter to its limits. Our NICER telescope aboard the International Space Station helped us precisely measure one called J0030 and found it had a radius of about twelve kilometers — roughly the size of Chicago! This discovery has expanded our understanding of pulsars with the most precise and reliable size measurements of any to date.

NASA Photographers Share Their #NASAMoonSnap
We’re getting ready to launch Artemis I, the first test flight of the rocket and spacecraft that will take future astronauts to the Moon! As we prepare for the lunar voyage of the Space Launch System (SLS) rocket and Orion spacecraft launching as early as Aug. 29, 2022, we would like you to share your excitement with us. Share all types of Moon-inspired content with us with the hashtag #NASAMoonSnap, and we will choose some entries to share on our social media platforms and during the launch broadcast. Get creative! We’re looking for Moon paintings, Moon poetry, Moon pottery, Moon latte foam art — the sky is not the limit.
Since we have the full Moon coming up on Aug. 11, we wanted to share our handy dandy Moon photography guide and inspire you with some of our NASA imagery experts’ stories on capturing the Moon.
"The first rollout of the SLS rocket with the Orion spacecraft aboard was a really exciting moment to capture. I was photographing at Kennedy Space Center in an area where many of the employees that had worked on different parts of the SLS were watching. It was so great to hear some of their stories and see their pride in helping to build this amazing rocket and spacecraft. Once the mobile launcher with SLS passed the crowds to head toward the launchpad, people began to line up in their cars to leave. I decided to stick around and try to get a closer image of the Moon with SLS. It was fairly dark by the time I made this image, so there isn’t any detail in the moon, but it’s still moving to see them next to one another and know that SLS will be closer to the Moon than Earth very soon, and will one day enable humans to land on the lunar surface again!" — Aubrey Gemignani, NASA contract Photo Archivist/Photographer, NASA Headquarters
“I set up this shot when I saw the Moon was lined up perfectly with the X-1E in front of the main entrance to Armstrong Flight Research Center one morning last year. What captured my eye about this scene was that it showcased the past and the future of NASA in one image. The X-1 was a key piece of early NACA/NASA history, and it is pointing to the Moon showing us where we are going next with Artemis. I still remember walking around on my first day at NASA and seeing all the places where history was made. I was in awe as I walked these hallowed grounds. I know that there is still a great deal of history to be written here as we strive to go higher, further and faster and I’m glad that I get to be here to document it.” — Joshua Fisher, Photographer, NASA’s Armstrong Flight Research Center
“While out capturing images of the Moon, the memories of my first day as a photographer for NASA came flooding back. One of my first memories is going to the exhibits department and getting to hold an actual Moon rock sample. That day changed my perception of the Moon forever. That moment made the Moon more than just something in the sky. It became tangible and real, and my part in all of this became clear. The honor and privilege I feel everyday is overwhelming.” — Jef Janis, Still Imaging Specialist, NASA’s Glenn Research Center
“When I can, I like my Moon photos to have a sense of place. The trick is finding a shooting position and a landmark that will fit in with the Moon’s very stringent plans for rising. I went out to shoot the Sturgeon Moon, which was also a rare blue moon, last August. As I was shooting the moonrise from the riverbank in downtown New Orleans, I was lucky to have one of the city’s iconic riverboats turn a bend and head upriver to pass beneath the Moon. Happily the river was low and I was able to scramble down the high bank to reduce the vertical distance between the quickly rising moon and the slowly passing riverboat.” — Michael DeMocker, Photographer, NASA’s Michoud Assembly Facility
“I was excited to try to capture a waning crescent Moon at dawn, even though it was late February, 20 degrees Fahrenheit and 6:30 in the morning…Nonetheless, I decided to photograph on-site at Lewis Field, and ended up using my telephoto lens to really zoom in on the Moon. In a race against the sunrise and the Moon disappearing, I was able to capture a cool shot of the Moon with a couple planes making an appearance as well (The Cleveland Hopkins Airport is right next door). Although is it me, or does one of the planes look like a rocket taking off…?” — Jordan Salkin, Scientific Imaging Specialist, NASA’s Glenn Research Center
“I have worked at NASA’s Glenn Research Center since 1990 and have enjoyed every second doing what I do to support NASA’s mission. On my first day back to work onsite after 22 months of telework I saw this beautiful sunrise with the snow, the Moon, and the hangar. It felt good to be at work seeing the landscape I was so used to seeing. I had to take these pictures to share with my colleagues. ” — Jeffrey F. Abbott, Media Support Specialist, NASA’s Glenn Research Center
“In creating this Moon image, I almost felt pressured to find the ‘perfect location.’ The more that I thought about that prospect, the more I was drawn to using only natural elements, in my own environment. I wanted to find an image in my own backyard. This image was captured just as the Sun dropped below the horizon. I had a very short window of time when these colors would be possible. Two minutes earlier or later would have produced a totally different image. The almost abstract lines of a Maple tree in the earliest stages of budding seemed to be in concert with the waxing crescent Moon, both preparing for full bloom. Nature on display in its simplicity.” — Marvin Smith, Still Imaging Specialist Lead, NASA’s Glenn Research Center
“The lighthouse in Lorain, Ohio, has been photographed by amateur and professional photographers for decades, but I have never photographed it before. When I calculated that the path of the Moon was going to go over and past the lighthouse with a reflection over the water, I decided to give it a try. I encountered four other photographers on the same pier with me that early morning. They were huddled in the middle of the pier and I was at the end. I think I got the best photo.” — Quentin Schwinn, Scientific Photographer, NASA’s Glenn Research Center

While most folks were sitting down for supper, NASA tried to move a space mountain.
Beyond sight for backyard stargazers, a spacecraft the size of a vending machine self-destructed by ramming into a harmless asteroid shortly after 7 p.m. ET Monday, September 26th. The high-speed crash was part of the U.S. space agency's Double Asteroid Redirection Test, or DART.
The moment of impact marked the first time in history humans have attempted to alter the path of an asteroid, a flying chunk of rubble left over from the formation of the solar system about 4.6 billion years ago. Most of the time, these ancient rocks pose no danger to Earth, including Dimorphos, the one NASA just used for target practice. But at least three have caused mass extinctions, the most infamous of which wiped out the dinosaurs.
Stegosaurus didn't have NASA.
"We are changing the motion of a natural celestial body in space. Humanity has never done that before," said Tom Statler, program scientist. "This was the substance of fiction books and really corny episodes of Star Trek from when I was a kid, and now it's real."

A harmonia entre espécies 😍
My dad Russell Kightley’s illustration of an animal cell (which includes humans too) has recently gone viral on the internet. I’ve always been very proud of his work. I used to take in big laminated posters (biocam.com) of his scientific illustrations into class to showcase the intricacies of various cells, including plant and animal, as well as different viruses, organisms etc. He also drew a Coronavirus life cycle in 2003 when SARS broke out; many people don’t realise but SARS was also Coronavirus, ‘Corona’ is Latin for ‘crown’ and refers to the crown like spikes around a particular virus.
From start; Animal cell, plant cell, coronavirus lifecycle, parameciums, amoeba.
My Favourite Curiosity Pictures from the Past Decade
The Mars Science Laboratory (MSL) aka Curiosity (above) landed on Mars at 10 (earth) years ago at the exact time of posting - 5:17 UTC on August 6th, 2012. Even before its landing I've been starry eyed over the mission, and the for almost three years I've been lucky enough to get to do science operations with the rover*. In honour of a decade of roving Gale Crater, here are some of my favourite pictures. (This will be a long post.)
*Standard disclaimer that nothing in this post or on this blog for that matter is at all associated with NASA or the CSA - opinions all my own!
I would be remiss to not start out with clouds - I LOVE this image - if you've ever seen me do a talk about Mars you've probably seen this picture. During the early part of the Mars year, clouds form in the twilight which are really high in the atmosphere and so can be illuminated even after the sun has gone below the horizon. These are called noctolucent clouds, and we also get them on earth! I also love this picture because it combines the two science teams - the environmental team and the geo team.
This is a panorama from Curiosity's landing site (Bradbury landing) and shows a fairly distant-looking Mount Sharp - the central peak of Gale Crater. It took MSL nearly two 9earth) years to reach the mountain, and since then we've been climbing it, travelling through the timeline of Gale as we move from older to younger sediments.
I love a blue sunset picture. This one is from fairly early on in the mission - less than 1000 sols (martian days) in (for reference - we're on sol 3554 now). The sunsets on Mars appear blue because of the scattering properties of dust in the atmosphere. Blue light is more effectively scattered forwards from the sun, but as the sun sinks and we look through more atmosphere, the blue light can spread out a bit.
This set of images was taken during the global dust storm of 2018 (Mars year 35), the one that spelled the end of Opportunity. Luckily, Curiosity uses nuclear power, not solar, and was able to weather the storm. It's so cool to watch the crater rim in the distance disappear, and the closer ground as well. The rover got well and truly socked in.
The final image I'm going to share is this delicate little "flower". When I first saw the MAHLI image (MAHLI = Mars Hand Lens Imager) I gasped out loud. I love cool looking rocks! This one is only a few centimetres tall but I love how much it really does look like a bit of coral or a flower (it isn't - Curiosity hasn't found plants on Mars).
